Collie played four seasons with the Indianapolis Colts. He was at camp with the San Francisco 49ers this season but was cut in August.

He caught more than 50 passes in three straight seasons, from 2009 to 2011, but played in only one game last year due to a knee injury. He has a history of concussion problems.

Collie, listed at 6 feet and 204 pounds, could give the Patriots another slot receiver option alongside Julian Edelman. Danny Amendola is continuing to work his way back from a groin injury, and it's not known when he will return to the field.

Sudfeld, a rookie out of Nevada, had been one of the big surprises in training camp with strong performances. They continued into preseason games. But he has struggled since the regular season began, having one pass in the opener go off his hands and get intercepted and failing to recover an onsides kick that bounced to him in last week's game at Atlanta.

The Pats also officially placed Vince Wilfork on injured reseve. Wilfork had surgery Monday for a torn right Achilles tendon.
